Shell Spirax S2 ATF AX
Shell Spirax S2 ATF AX is a high-quality automatic transmission fluid developed to provide reliable performance across a wide range of automotive transmission, power steering and hydraulic system applications. Formulated with high-quality base oils and advanced additive technology, the lubricant delivers smooth shifting performance, strong wear protection and excellent oxidation resistance. The fluid is designed to meet the demanding requirements of both passenger car and heavy-duty vehicle transmission systems, as well as certain hydraulic applications.
One of the key advantages of Shell Spirax S2 ATF AX is its friction-modified formulation, which helps ensure smooth and consistent operation of automatic transmission systems. The carefully balanced friction characteristics allow transmission clutches and bands to operate efficiently, helping provide smooth gear engagement and reliable shift performance. This helps reduce transmission shudder and contributes to a comfortable and responsive driving experience.
Shell Spirax S2 ATF AX also offers excellent oxidation resistance. Automatic transmission fluids are exposed to high operating temperatures and mechanical stress during operation, which can accelerate oil degradation. The advanced additive system helps resist oxidation and maintain fluid stability, helping ensure consistent lubrication performance and extended fluid service life. This helps reduce the formation of harmful deposits that could interfere with transmission performance.
Another important benefit of Shell Spirax S2 ATF AX is its excellent shear stability. Transmission fluids must maintain their viscosity even under severe mechanical stress. The formulation includes a specially designed viscosity index improver that helps the fluid remain within its intended viscosity grade over extended service periods. Maintaining stable viscosity ensures reliable lubrication of gears, bearings and hydraulic components within the transmission system.
Shell Spirax S2 ATF AX also delivers dependable anti-wear protection for critical transmission and hydraulic system components. The advanced additive system helps protect gears, bearings and hydraulic pumps from wear and surface damage. This contributes to longer component life and improved reliability of transmission and hydraulic systems in both passenger vehicles and heavy-duty equipment.
The fluid is suitable for a wide range of automotive and industrial applications including passenger car automatic transmissions, heavy-duty automatic transmissions, power steering systems and hydraulic power systems. It meets the performance requirements of several major equipment manufacturers and transmission systems, including Ford MERCON®, ZF TE-ML 03D, 04D, 09, 11A and 14A, Voith 55.6335, MAN 339 Type Z1 and V1, and Mercedes-Benz MB-Approval 236.7. It is also suitable for applications requiring Allison C-4 or Dexron IID type fluids. Physical characteristics include a kinematic viscosity of approximately 34.6 mm²/s at 40°C and 7.1 mm²/s at 100°C with a viscosity index of approximately 174, a density of approximately 874 kg/m³ at 15°C, a flash point of approximately 180°C and a pour point of approximately –45°C.
